Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 746790-1 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector style: D-Sub
• Connector type: Plug, Male Pins
• Number of positions: 50
• Number of rows: 3
• Shell size and layout: 5 (DD, D)
• Termination method: IDC, Ribbon Cable
• Contact type: Signal
• Flange feature: Housing/Shell (4-40)
• Operating temperature range: -55°C ~ 105°C

Direct Equivalent Classification: The TE Connectivity 1658607-1 meets all primary substitution criteria and is classified as a direct equivalent. This part maintains identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Similar Substitute Classification: The 3M 8250-6005 shares the core D-Sub 50-position configuration and IDC termination but differs in mounting type (panel mount versus free hanging) and current rating (1A versus 1.25A). This part functions as a similar substitute where mounting configuration and current capacity adjustments are acceptable within system design parameters.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The TE Connectivity 1658607-1 is the recommended direct substitute for the obsolete 746790-1. Both parts maintain identical mechanical and electrical specifications, including 50-position configuration, 3-row layout, free-hanging inline mounting, and 1.25A current rating. The 1658607-1 offers the additional advantage of active product status with ROHS3 compliance and UL94 V-0 flammability certification, addressing regulatory requirements that the original part does not meet. Inventory availability of 63,100 units ensures supply continuity.

For Alternative Applications (Conditional): The 3M 8250-6005 functions as a similar substitute where system design accommodates panel mount configuration instead of free-hanging inline mounting. The reduced current rating of 1A requires verification that circuit requirements do not exceed this specification. The 8250-6005 provides ROHS3 compliance and UL94 V-0 certification. This part is suitable for applications where mounting flexibility and regulatory compliance take precedence over current capacity matching.

Compliance Considerations: Both substitute parts achieve ROHS3 compliance and UL94 V-0 flammability ratings, addressing modern regulatory standards that the obsolete 746790-1 does not satisfy. Selection should prioritize the 1658607-1 for applications requiring exact electrical and mechanical parameter matching.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1658607-1 be used as a direct replacement for the 746790-1?

A: Yes. The 1658607-1 maintains identical specifications across all critical parameters: 50-position D-Sub plug configuration, 3-row layout, shell size 5 (DD, D), IDC ribbon cable termination, free-hanging inline mounting, 1.25A current rating, and -55°C to 105°C operating temperature range. The primary differences are product status (active versus obsolete) and enhanced compliance certifications (ROHS3 and UL94 V-0).

Q: What are the key differences between the 1658607-1 and 8250-6005?

A: The primary differences are: (1) Mounting type—1658607-1 is free-hanging inline while 8250-6005 is panel mount; (2) Current rating—1658607-1 is rated 1.25A while 8250-6005 is rated 1A; (3) Manufacturer—1658607-1 is TE Connectivity while 8250-6005 is 3M; (4) Shell finish—1658607-1 has tin plating while 8250-6005 has nickel plating; (5) Dielectric material—1658607-1 uses thermoplastic while 8250-6005 uses glass-filled PBT polyester. Both maintain the 50-position D-Sub configuration and IDC termination method.

Q: Is the 8250-6005 suitable for applications requiring 1.25A current capacity?

A: No. The 8250-6005 is rated for 1A maximum current, which is 0.25A below the 746790-1 and 1658607-1 specifications. Applications requiring 1.25A current capacity must use the 1658607-1 or original 746790-1.

Q: What packaging formats are available for these parts?

A: The 746790-1 is supplied in unspecified packaging with 1,125 units in stock. The 1658607-1 is supplied in bulk packaging with 63,100 units available. The 8250-6005 is supplied in tray packaging with 701 units available.

Q: Are there compliance or regulatory differences between these parts?

A: Yes. The 746790-1 is RoHS non-compliant with no specified flammability rating. Both the 1658607-1 and 8250-6005 are ROHS3 compliant with UL94 V-0 flammability certification. For applications subject to RoHS or flammability regulations, the 1658607-1 or 8250-6005 must be used.

Q: Can the 8250-6005 be used in free-hanging inline applications?

A: No. The 8250-6005 is designed for panel mount configuration. Applications requiring free-hanging inline mounting must use the 746790-1 or 1658607-1.
